The apparatus according to claim 7, wherein a degree of curvature of the forming face gradually increases in the conveying direction of the glass sheet. 9. The apparatus according to claim 7, wherein the forming face is also curved in the conveying direction of the glass sheet. 10. The apparatus according to claim 7, wherein the conveying passage gradually deviates from a direction in which the glass sheet is conveyed from the heating furnace. 11. The apparatus according to claim 7, further including a cooling apparatus for quenching or annealing the glass sheet adjacent to the bending apparatus. 12. The apparatus according to claim 11, wherein the cooling apparatus includes a curved conveying passage for the glass sheet that has a predetermined curvature with respect to the conveying direction of the glass sheet.
